+
+break
+=====
+
+``break`` is used to exit from a :ref:`while <lang-while>`\ ,
+:ref:`for <lang-for>`\ , or :ref:`do/while <lang-dowhile>` loop,
+bypassing the normal loop condition. It is also used to exit from a
+:ref:`switch <lang-switchcase>` statement.
+
+
+Example
+-------
+
+::
+
+ for (x = 0; x < 255; x ++)
+ {
+ digitalWrite(PWMpin, x);
+ sens = analogRead(sensorPin);
+ if (sens > threshold){ // bail out on sensor detect
+ x = 0;
+ // this line of code means that we'll immediately exit
+ // from the "for" loop:
+ break;
+ }
+ delay(50);
+ }
